    This goes in the documents header:
    <pre class="code">
&lt;script src="RGraph.common.core.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.bar.js"&gt;&lt;/script&gt;
</pre>
    
    Put this where you want the chart to show up:
    <pre class="code">
&lt;canvas id="cvs" width="600" height="250"&gt;
    [No canvas support]
&lt;/canvas&gt;
</pre>

    This is the code that generates the chart:
    <pre class="code">
&lt;script&gt;
    var data1 = [[2,5,9],[4,2,6],[6,5,8]],
        data2 = [[-2,-1,-6],[0,0,-6],[0,-5,-8]];


    new RGraph.Bar({
        id: 'cvs',
        data: data1,
        options: {
            gutterLeft: 35,
            shadow: false,
            strokestyle: 'rgba(0,0,0,0)',
            noaxes: true,
            ylabels: false,
            colors: RGraph.ISOLD ? ['black','black','black'] : ['Gradient(black:#aaa:black)', 'Gradient(black:#aaa:black)', 'Gradient(black:#aaa:black)'],
            hmargin: 25,
            backgroundGridAutofitNumvlines: 3,
            xaxispos: 'center',
            'text.size': 14,
            ymax: 10,
            textAccessible: true
        }
    }).wave();

    new RGraph.Bar({
        id: 'cvs',
        data: data2,
        options: {
            gutterLeft: 35,

            colors: RGraph.ISOLD ? ['red', 'red', 'red'] : ['Gradient(red:#faa:red)', 'Gradient(red:#faa:red)', 'Gradient(red:#faa:red)'],
            hmargin: 25,
            xaxispos: 'center',
            'text.size': 14,
            backgroundGrid: false,
            ymax: 10,
